ABSTRACT:
Electrochromic devices are described having a layer of electrochromic material, e.g. WO.sub.3, in contact with a layer of organic electrolyte resin, with electrode means for changing electrochromic properties of the device by electric field means. The electrolyte resin layer comprises a hydrophilic layer of homopolymer of poly(2-acrylamido-2-methylpropanesulfonic acid) with an organic humectant and in some preferred embodiments may further comprise a thinner layer of less hydrophilic electrolyte resin between the homopolymer and electrochromic layers.
